OBJECTIVES:We aimed to characterize the intrinsic AmpC β-lactamase (EMC-2) from an Escherichia marmotae clinical isolate recovered from a bloodstream infection, exhibiting resistance to broad-spectrum cephalosporins. METHODS:Cloning experiments in Escherichia coli were performed to evaluate the impact of the respective AmpC enzymes on β-lactam susceptibility. Purification of the enzymes was performed by ion-exchange chromatography, and kinetic assays were performed by UV spectrophotometry. RESULTS:By comparing the sequence of this AmpC with that of a WT E. marmotae, four amino acid substitutions and one amino acid deletion at position 296 were identified. Furthermore, a promoter alteration was responsible for an enhanced gene expression. Production of EMC-2 in E. coli TOP10 conferred an extended-spectrum AmpC (ESAC) phenotype characterized by increased MICs of cefotaxime, cefepime and cefiderocol. Site-directed mutagenesis confirmed the important role of the Arg296 deletion in this phenotype. CONCLUSIONS:We showed that the intrinsic AmpC of E. marmotae can acquire both structural and regulatory modifications that broaden its substrate spectrum, leading to reduced susceptibility to clinically relevant β-lactams, including cefiderocol.
Understanding how nurse researchers perceive and utilize this technology offers insights into its integration within the nursing education system in the Philippines and globally, The study described Filipino nurse researchers' knowledge, perception, and attitudes toward ChatGPT and research productivity. Using a descriptive correlational design, self-made, validated, and piloted questionnaires were sent to three hundred seventy Filipino nurse researchers, both novice (<5 years of research experience) and seasoned (> 10 years of experience). Descriptive statistics were used for profile characteristics, while an independent sample t-test was used to identify significant differences between the two groups of participants in KPA and research productivity. Pearson's product-moment correlation and a standard linear regression analysis examined the relationship between the independent (KPA) and dependent (research productivity) variables. The level of statistical significance was set at p < 0.05. The largest participant group comprised female Filipino nurse researchers aged 20-30 with Master's degrees in Nursing. They reported having less than 10 years of experience as instructors and having published 1-5 research articles. The KPA scores indicated a general understanding of ChatGPT’s capabilities, as a valuable tool for research and positive regard toward its use. The study findings further revealed that the t-test did not show a statistically significant difference in perception (t=1.28, p=0.20) and research productivity (t=1.28, p=0,20). But knowledge (t=4.73, p=0.00) and attitude (t=1.28,p=0.02) were found to be significant. Further analysis revealed an adjusted R-square of .145, indicating that the independent variables (knowledge, perception, and attitude) can explain approximately 14.5% of the variance in research productivity. A statistically significant positive correlation was found between attitudes toward ChatGPT and research productivity (β = 0.141, p = 0.012). This study comprised female instructors aged 20-30 with Master's degrees in Nursing and less than 10 years of experience. They reported having 1-5 publications, suggesting moderate research activity. While the findings revealed a general understanding of ChatGPT's potential for research, participants hesitated to integrate its use due to ethical concerns, which need further education on the responsible use of ChatGPT in research. Moreover, study findings suggest that Filipino nurse researchers who are more open to using ChatGPT tend to demonstrate greater research output.
This thesis study entitled “Organizational Commitment, Adaptive Performance and Job Satisfaction of Hotel Employees in Region XII” investigated the level of organizational commitment, adaptive performance and job satisfaction of hotel employees and designed to yield an intervention program that will help increase if not sustain the above-mentioned variables. The study consisted of 10 problems and 3 hypotheses. The research instrument which was an adapted 4-part questionnaire was administered to 782 hotel employees, 91 of which are managers/administration and 691 are employees of two-to-four stars hotels in Region XII accredited by the Department of Tourism to examine the level of organizational commitment, adaptive performance and job satisfaction of hotel employees. It used the descriptive research design particularly descriptive normative survey and correlational research to determine the level of organizational commitment, adaptive performance and job satisfaction of hotel employees. The paradigm of the study was the IPO (input, process, and output) where each variable was thoroughly discussed in the review of related literature and studies. The data were statistically analyzed using the frequency count, percentages, mean, standard deviation, t-test, ANOVA and Pearson r. The result shows that respondents were often committed to the organization, often performed adaptively and often satisfied with their job. The hotel is therefore, urged to improve the level of organizational commitment, adaptive performance, and job satisfaction of hotel employees. Relative to the result of the study, an intervention program in a form of revisiting the policy manual and strategic planning is proposed.
Concrete is the most widely used construction material, but its environmental impact and reliance on finite resources have driven the need for more sustainable solutions. This research paper presents the optimization of bamboo fiber and wood ash as supplementary materials in concrete to enhance its mechanical performance and sustainability. A powerful statistical technique known as Response Surface Methodology was employed to systematically investigate the effects of varying bamboo fiber and wood ash content on the compressive and flexural strengths of concrete. The optimal combination of 0.36% bamboo fiber and 13.43% wood ash resulted in a flexural strength of 3.227 MPa and a compressive strength of 18.444 MPa, demonstrating the significant potential of these sustainable materials to improve concrete's mechanical properties. The findings of this study provide valuable insights for the construction industry, highlighting the feasibility of utilizing bamboo fiber and wood ash to develop more durable and environmentally friendly concrete mixtures that can contribute to a more sustainable built environment.
